  3. Ozone layer - Wikipedia

    en.wikipedia.org/wiki/Ozone_layer

    The ozone layer visible from space at Earth's horizon as a blue band of afterglow within the bottom of the large bright blue band that is the stratosphere, with a silhouette of a cumulonimbus in the orange afterglow of the troposphere. The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet ...

    en.wikipedia.org/wiki/Ozone_depletion

    Following the ozone depletion in 1997 and 2011, a 90% drop in ozone was measured by weather balloons over the Arctic in March 2020, as they normally recorded 3.5 parts per million of ozone, compared to only around 0.3 parts per million lastly, due to the coldest temperatures ever recorded since 1979, and a strong polar vortex which allowed ...

    Relationship of the atmosphere and ionosphere. The ionosphere (/ aɪ ˈ ɒ n ə ˌ s f ɪər /) [1] [2] is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, [3] a region that includes the thermosphere and parts of the mesosphere and exosphere.

    Norman-style kite shield. [1]A kite shield is a large, almond-shaped shield rounded at the top and curving down to a point or rounded point at the bottom. The term "kite shield" is a reference to the shield's unique shape, and is derived from its supposed similarity to a flying kite, although "leaf-shaped shield" and "almond shield" have also been used in recent literature.

  7. Space Shuttle thermal protection system - Wikipedia

    en.wikipedia.org/wiki/Space_Shuttle_thermal...

    The key to a reusable shield against this type of heating is very low-density material, similar to how a thermos bottle inhibits convective heat transfer. [citation needed] Some high-temperature metal alloys can withstand reentry heat; they simply get hot and re-radiate the absorbed heat.

    A capping inversion limits the vertical development of clouds. In this image taken near Kreuzberg (Rhön), the inversion is below the top of the mountain tops. Diagram showing the daily changes to the capping inversion on top of Earth's planetary boundary layer.
